Iron Loss Tester Model: DW‐21 is very accurate single sheet iron loss tester. You can evaluate very accurate watt loss of any electrical steel sheet by feeding it's accurate weight or thickness in the instrument. You can test the sample from 0.2 Tesla to 1.8 Tesla at frequency range from 35Hz to 125Hz.

Digital watt loss tester Model RK45 is very useful instrument for comparing different motor stampings grade. It is very much important to inspect the grade and watt losses of motor stamping for high quality and energy efficient motor development.

Franklin tester measures the surface insulation resistivity of single strip of flat‐rolled electrical steel under predetermined conditions of voltage, pressure, and temperature according to ASTM A717 & IS649
